Cobbora Coal has adjusted its plans for an open cut mine near Dunedoo after receiving more than 200 submissions.

Many of the individuals and community groups oppose the project, while state and federal agencies want certain issues clarified.

The planning process is continuing despite legislation passing governing its operation and the sale of the state's power assets.

The company now wants to use more than 4000 megalitres each year, an increase of around 15 per cent.

The mining area is also expanding by 180 hectares to around 4000 hectares.

Cobbora says the changes are 'unlikely to distort the water market'.

But it says it needs to buy another nine-hundred megalitres worth of water licences to fulfil its requirements.

The Cobbora Holding Company says it has given careful consideration to the feedback provided in the submissions.

It says water used on site will be mainly harvested surface water and water collected at the mine.

The company says it has a water licence allowing extractions from the Cudgegong River, but that it is working with State Water to ensure as much of its entitlement as possible is extracted during periods of excess flows.
